Aserial No. 143,349.

pneumatic conveyer provided at one end with an inta-ke 1G which rec vosair under pressure fronr a suitable The duet or trunk 1,5 has alongitanlinul partition 17, one end of which spaced from thc intake 16,while the other end of said partition. may extend to the lifwhfn'go ond18 Vof the duct. The trunk or (niet thus. divided into two'iongitucr'm!E es A l iii -'rs :it f1 distance from the int-alie end ci duct with ,anapproximately sembri audrical rei-'ti cal shaft 20, said shaft beingconcentric with the arcuate wall of' the chainiver, and Saidshaftcarrying a plurality of Wing-s or blades 21 which are of suchdimensions as to extend at one side to the partiion Tvall 17 'and at theother side to the nah of the chamber 19, said blades being, moreover,curved transversely so as to present concave A l 1 faces 1n thedirection of 'the alr intake 1h.

Mounted on the top wall of the trunk or mately cylindrical shape, 'saidcasing having feeder casing has a hopper 25 which receives from anysuitable source of supply., such as a gin casing, not shown, thematerial, such as cotton seed, that is to be handled by the pneumaticconveyer. The shaft 24 is provided with' radially extending wings havinI'iiexible brushes .27 of leather, rubber or ot 1er material.adjustal'ily connected therewith by clamp plates 2S, the constructionlbeing such that as the brushes heemne worn the ma` be ad usted toenafre 'the arcuate y e D Walls of the feeder casing'. A sullicient,number of brush carrying ivings should be placed on the shaft 24 toconstantly form' an air tight closure between the hopper 25 and thepassage B when the machine. is in operation.' The shaft is providedadjacent to the end Walls 23 with packing disks 29,

`One end'o the shaft carries a worm gear 30 meshing with a' worm. 31 on'the vertical shaft 20, thus causing the feeder shaft to be'driven -hythe vertical shaft 2() when the latter is rotated.

Mounted in the trunk or duct-.'15 adjacen tothatwend of the partition l?which faces the intake 16 is a vertical shaft 32 carrying a .valgffothatextends in the direction of source ol supply.

the intake. The shaft 32 has an operating lever 34 )lorovided with aspring actuated stop mem er 35 enga-ging a segment rack 36 for 'thepurpose of retaining the valve Ain any position to which it may beadjusted.

It will be seen' that by proper manipulation of the lever 34 the valve33 may be adjusted so as to direct the inrushing air current into eitheroneof the passages A and B, or partly into each of said passages,

the proportion of air entering either passagebeing regulated by the.position of the valve.

-. The shaft 20 having the arcuate blades 2.1

constitutes a motor whichiis driven by the air current passing throughthe passage A, said motor serving to drive the shaft of the feeder,causing material to drop into the pasthe valve may be changed to deflectthe entire air current into the passage B carrying' the accumulatedmaterial to the point of dis: charge.

Having thus described the invention, what is claimed as new, isq- 1. Ina pneumatic ,'conveyer, a wind trunk having two passages, a feedercommunicatingwith one passageand havingan operating shaft, a pneumaticmotor having blades extending within the other passage of the windtrunk, and means fdr transmitting power from said motor'to the feedershaft.

2. In a, pneumatic conveyer, a wind trunk having two passagesjafeedercommunicating with one passage and having an. operating shaft, apneumatic mptor having blades extending within the other passagev of,the wind trunk, means for transmitting power from said motor to theVfeeder shaft, and valve means for controlling the delivery of anincoming air current to the two passages.

3. In a pneumatic conveyer, a wind trunk having a partition forming twolongitudinal l A n u passages, a feeder communicating with -one passage,said feeder having'an operating shaft, a pneumatic motor having wingsexlshaft for driving the latter.

- 4. In a pneumatic conveyor, a wind trunk having a-partition wherebytwo longitudinal passages are formed, a feeder communicating with onepassage, a pneumatic inotor comprising a shaft having wings extendinginto the other passage in the direction of the partition, transmissionmeans between the motor shaft and the feeder shaft, and a valve 'supOrted. in the intake cud of the wind trun adjacent to one end of thepartition.

5. In a pneumatic conveyer, a wind 'trunk having an air intake at oneend provided with a partition forming tivo longitudinal passages, avalve supported adjacent to one end of the partition and extending inthe direction of the intake end of the trunk to regulate the incomingair current, a feeder communicating with one passage, a pneumatic motorcomprising a shaft having wings or blades extending into the otherpassage in the direction of the partition, an operating' shaft extendinglongitudinally through the feeder and having a worm gear, and a worm onthe motor shaft meshing with said gear.

In a pneumatic' conveyer, a wind trunk having a partition forminglongitudinal passages, an approximately cylindrical feeder casingcommunicating -with one passage and having a hopper to receive material.from a source of supply` a shaft extending longi- .tudinally through thefeeder casing and having wings provided with brushes engaging thearcuate walls of the casing, a pneumatic motor opera-ble by an aircurrent passing through the other passage, means for transmitting motionfrom the motor to the feeder shaft, and a valve to regulate an aircurrent passing through the wind trunk and to deect such air currentwith respect to the passaifes of said trunk.
